This will lose Labor the Election

https://www.news.com.au/finance/economy/budget-reveals-labor-pushing-ahead-with-tax-on-unrealised-capital-gains-for-superannuation/news-story/1362357fc3b588d77f1d806af7ac4a64

Forget that its super which is designed so that people can pay for their own retirement rather than the tax payer

But how can you tax "unrealised gains"

I've invested in stocks that have gone up 300% only to realise a loss in the end. If i get taxed on the unrealised profits would i then get a refund on my loss? Will the super funds?

While i dont agree with their rhetoric around negative gearing tax relief I can understand why but this is just sheer stupidity

Thoughts?
